摘要： An optical apparatus configured to guide light from an object to an image pickup element includes a first light amount adjustment unit configured to change transmissivity or the light from the object through change in physical property thereof. Then, in recording, a second light amount adjustment unit configured to mechanically change an area through which the light from the object passes is prevented from being driven but the first light amount adjustment unit is driven to adjust an amount of the light from the object entering the image pickup element.

摘要： An adaptor is attachable between an interchangeable lens including a first light amount adjustment unit capable of changing a passing area of image pickup light, and a camera main body including an image pickup element. The adaptor includes: a second light amount adjustment unit capable of changing transmittance of the image pickup light by using a change in a physical property; and a controller controlling the second light amount adjustment unit. In image pickup mode, the controller controls the transmittance in the second light amount adjustment unit depending on an operating amount of an operation unit by a user to adjust a light amount, and in the image pickup mode, the controller converts an instruction, transmitted toward the interchangeable lens from the camera main body, to drive the first light amount adjustment unit, into a drive completion signal, and transmits the drive completion signal to the camera main body.

摘要： A lens apparatus includes an imaging optical system, a movable member holding at least one of lenses and configured to move in a direction including a component perpendicular to an optical axis of the imaging optical system, a fixed member whose movement in the direction is restricted, a coil provided at one of the movable member and the fixed member, a magnet provided at the other of the movable member and the fixed member, and a first shield member configured to cover at least a part of the coil as viewed in a direction parallel to the optical axis and as viewed in the direction perpendicular to the optical axis. At least a part of the first shield member being arranged closer to an image plane than the coil, and a predetermined conditional expression is satisfied.
